Ingame command functions.

Greetings. Not sure if this has been addressed but certain commands does not seem to work. Being from XI one of my first things I did in this game was /? command to get a list of commands so I know what I am working with. It has never worked. I figured it was just removed from the game. However going through the auto translate I found /? command there. I used the auto translated version and it still came up with an error. I don't know how many more commands are not working but thought to bring it to your attention. Thank you for your time in this matter.
